Odd resolving problem

Hello,
My DNS servers suddenly stopped resolving one particular hostname,
while others around the globe can resolve this host just fine.
The hostname is irc.quakenet.org (and a CNAME of it:
irc.quakenet.eu.org).
Other hosts that are in the same domain and have the same authorative
nameservers resolve fine, i.e. www.quakenet.org and
irc.uk.quakenet.org.
I'm running BIND 8.2.0 on Windows 2000 Advanced Server SP2.
I included some dig's to show my problem at the end.
The last dig is a lookup of irc.quakenet.org through some other DNS
server, and it shows a lot of A records for this host. So I figured the
answer might be bigger than a UDP packet and I could be accidentally
blocking port 53 TCP. This is not the case.
And I'd like to note that until some hours ago the host resolved fine.
Does someone have an idea what this could be? The logs don't give me
any clues.
Thanks in advance.
